Sudoku: Fill every row, column and marked 3x3 box with the digits 1-9.
Region Sum Lines: Digits on a line must have an equal sum within each region is passes through.
Entropy: The low digits (1, 2, 3), middle digits (4, 5, 6) and high digits (7, 8, 9) are defined as three different groups. In the finished grid each 2x2 box has to contain at least one digit of each group.
Have fun solving!

Great puzzle! If this was my first global entropy puzzle, I would have rated it 5 stars, but I have learned that your 5 stars puzzles are completely melting your brain to atoms and this one didn't in the end, so 4 stars is probalbly right. Thank you!

It always feels like an accomplishment solving an entropy puzzle... definitely not my forte but this one was well worth the effort. One of the simplest yet most clever break-ins I've seen in a long time. Well done!
